I had a TT about a year after diagnosis. If I didn't, my nodules were going to have to be biopsied, according to my doctor. It did turn out that I had a very tiny "Microcarcinoma", but I doubt it was either of the nodules picked up on my initial ultrasound/scan.
There is some evidence that Graves can be hereditary, but the more common thought is that nobody really knows what causes Graves.
I think I have read that there is no significant increase in cancer in those who have had RAI vs. the general population. Hopefully, someone else has more experience than I do with RAI and can give you a better answer.
Thank you!
